Python is a powerful programming language. It is very friendly and easy to learn. During the latest update of this article, Python 3.9.16 (of the Python 3.9 series) latest stable version is available to download and install.
This tutorial will help you to install Python 3.9 on Amazon Linux systems.
Installing Python from the source code requires a GCC compiler. So must have installed the required development libraries first.
Open a terminal on your system and install the prerequisites for Python:
sudo yum install gcc openssl-devel bzip2-devel libffi-devel
Step 1 – Download Python 3.9
Visit Python’s official download page and download the required Python on your system. Alternatively, You can use the following command to download Python 3.9 on a local machine.
After the download is finished, extract the archive file.
sudo tar xzf Python-3.9.16.tgz
Step 2 – Install Python 3.9
Switch to the extracted directory with the cd command. Then use the ./configure script to prepare the source code. After that, you can compile and install it with the make command. Below set of commands to compile Python 3.9 from the source code and install using the altinstall command.
sudo ./configure --enable-optimizations
sudo make altinstall
make altinstall is used to prevent replacing the default python binary file /usr/bin/python.
Now remove the downloaded source archive file from your system
sudo rm -f /opt/Python-3.9.16.tgz
Step 3 – Check Python Version
The Python 3.9 binary is installed under /usr/local/bin directory. As we have not overwritten the current Python version, you need to run Python 3.9 command as follows:
python3.9 -VPython 3.9.16
Step 4 – Create Python Virtual Environment
Python provides to create an isolated environment for the applications. Where you can create an environment directory with a specific Python version. This will contain application-specific packages.
Use the following command to create an environment directory:
python3.9 -m venv env
The above command will create a directory “env” in the current directory containing all the required files for the isolated environment.
Every time you need to make changes in the environment, Use the below command to activate it.
After activating the environment, you can work with your application.
Once your work is finished, use the following command to deactivate the Python environment.
In this tutorial, you have learned to install Python 3.9 on Amazon Linux using source code.
